The controller e2e for #72 has to exercise the operator under each of its webhook and serving-cert arrangements, and wants a cluster carrying nothing but the base. up.sh could do neither. KARTA_WEBHOOK_MODE selects the arrangement. auto keeps the chart default, where the operator self-signs and rotates its own cert and patches the caBundle onto its webhook configs. cert-manager switches the chart to provisionMode=manual, where the operator never touches the cert or the caBundle; the chart ships no Issuer or Certificate for that mode, so up.sh supplies them and waits for the Secret before installing. disabled drops the webhook entirely, which is the only arrangement where an invalid Karta CR is admitted and reports Validated=False instead of being rejected at admission. WORKLOADS=none installs the base alone, so a controller e2e run does not pay for ten upstream operators it never touches. cert-manager is now installed only when something needs it: the cert-manager route, or kserve, whose bundled manifest ships Certificates that cainjector owns. Leaving it out is the point rather than a saving, since a cluster without it is what proves the operator's own cert controller depends on nothing external. CERT_MANAGER forces the decision either way and fails fast when false contradicts the plan. Signed-off-by: sbouktus <sbouktus@nvidia.com>

can't we do it in the test that test the webhook ? instead of putting it under the up.sh
…eady install_karta_certificate waited only for the Certificate. cainjector cannot stamp the caBundle until the annotated webhook configs exist, and helm creates those after that wait, so nothing gated on the injection: up.sh could report the environment ready while the API server still had an empty caBundle, and the first admission call would fail with an x509 error that looks nothing like the cause. The auto route was never exposed to this. There the operator's own rotator writes the caBundle before it reports ready, so rollout_wait is an implicit gate. Manual mode removed that gate without replacing it. wait_for_ca_injection polls both webhook configs after the install, on the cert-manager route only. install_karta now returns 0 explicitly, since a trailing [ test ] && cmd would return 1 on the other two routes and set -e would abort the provision. Also document that each route wants its own CLUSTER_NAME. up.sh reuses an existing kind cluster, and the cert-manager route leaves cert-manager and the Certificate behind; that Certificate keeps reconciling the same Secret the auto route's operator writes, so the two contend and the no-cert-manager claim stops holding. CI is unaffected, since a fresh runner has no cluster to reuse. Signed-off-by: sbouktus <sbouktus@nvidia.com>
up.sh had grown from 253 to 415 lines, most of it the three webhook routes and their cert handling, which left it doing the job it documents as the workload operators' own: a standalone install script per component. install-karta-operator.sh follows that same convention (MODULE_DIR, sources _common.sh, main(), exit-code contract) and holds the webhook resource names, the certificate issue, the CA-injection wait and the route selection. up.sh runs it last, as a subprocess, and is back to orchestrating at 316 lines. Karta is the system under test rather than cluster infrastructure, which is why this sits beside operators/ instead of inside it: a directory there would imply WORKLOADS=karta selects it. The route is validated in both places on purpose. up.sh validates so --list rejects a typo without provisioning, and the script validates again so it is safe to run on its own against the current context, which is now the fast way to reinstall Karta without rebuilding the cluster. Also add the new script to E2E_SHELL so lint-shell covers it. Signed-off-by: sbouktus <sbouktus@nvidia.com>

shellcheck SC2034: the poll loop's counter is never read, so name it _ rather than i. Fixed instead of suppressed, per the no-disabling-lint-rules rule. Caught by CI because make lint-shell had never run locally; shellcheck is not installed on this machine, and the run that verifies this fix went through the koalaman/shellcheck:stable image instead. All 24 scripts in E2E_SHELL pass. Signed-off-by: sbouktus <sbouktus@nvidia.com>

AGENTS.md asks for short sentences in markdown, and three passages had drifted well past that: the cluster-reuse warning, the installer and certificate lifecycle, and the fresh-cluster qualification on the no-cert-manager claim. The worst ran to about fifty words stacking a colon and two "and" clauses. Split by topic rather than only at sentence boundaries, so each paragraph makes one point: what the script is, what the chart omits, why the certificate has to precede the helm install, and what wait_for_ca_injection covers afterwards. Every technical detail is kept, including the shared-Secret contention between the two routes and the crashloop-rather-than-wait startup behaviour. Signed-off-by: sbouktus <sbouktus@nvidia.com>

Part of #72. Does not close it: the controller e2e suite itself is the next slice.
